Chapter 8, Problem 12PP

Write a program that inputs a time from the console. The time should be in the format "HH:MM AM" or "HH:MM PM". Hours may be one or two digits, for example, "1:10 AM" or "11:30 PM". Your program should include a function that takes a string parameter containing the time. This function should convert the time into a four-digit military time based on a 24-hour clock. For example, "1:10 AM" would output "0110 hours", "11:30 PM" would output "2330 hours", and "12:15 AM" would output "0015 hours". The function may either write the time to the console or return a string to be written to the console by the main function.
